Technical field
The battery that the utility model relates to battery cover board assembly and used this cover plate assembly.
Background technology
Existing battery generally comprises housing, cover plate and pole.For part battery wherein, as present electrokinetic cell (being big capacity, high power rechargeable battery), for rising, the pressure anomaly that prevents inside battery makes cell fracture, need be to outside release pressure when extraordinary risings of interior pressure, thereby the relief valve device of installation on the cover board also.
Battery container, cover plate are divided into plastics and metal is good for both sides, and pole then can only be electric conducting material, and is in the majority with metal.
Wherein the wall thickness of plastic casing and plastic cover plate is generally thicker, otherwise is difficult to bear bigger pressure, easy bulging, thereby its volumetric specific energy is lower, but plastic casing is in light weight, and specific energy is higher relatively.On the other hand, because plastics itself are insulators, so pole can be by directly fixing on the cover board.
And metal shell and metal cover board generally have steel, aluminium etc., and metal shell and cover plate intensity are good, and wall thickness can be done thinlyyer, thereby its volumetric specific energy is higher.Wherein the safety valve of metal shell battery generally all is that metal material is made, by the welding or bolt on the cover board, this structure more complicated, with high costs, and safety valve installing and fixing on metal cover board is very difficult, in battery assembling or connection procedure, clamp nut when mounted, safety valve probably can be followed together and to rotate, thereby is difficult to fasteningly, and the problem of leaking also appears in battery easily in the future.There are same technical problem in the installation of the pole of existing battery and sealing and above-mentioned safe installation and sealing.
Fig. 1 shows the schematic diagram of existing battery.As shown in the figure, battery cover board 140 is installed on the housing 100 of battery, is formed the battery of complete closure.Positive terminal 110, negative terminal 130 are installed on battery cover board 140, and pole is fixing on the cover board by nut, and megohmite insulant is installed in the middle of both, as insulating washer, realizes insulation.Safety valve 120 is installed simultaneously, is installed on the battery cover board 140, and communicate in inside battery by screw connector 121.
The utility model content
Technical problem to be solved in the utility model is for the metal cover board and safety valve, pole installation process more complicated that overcomes existing battery, and the technical problem that is difficult to fastening, easy appearance leakage in the process of installing and fixing.A kind of new battery cover board assembly and the battery that has used this battery cover board are provided.
The technical scheme that realizes technical problem to be solved in the utility model and take is summarized as follows:
On the one hand, a kind of battery cover board assembly is provided, comprise metal cover board and pole with through hole, also comprise clamp, described clamp is made by insulating material, has through hole on the clamp, pole is fastened on the metal cover board after passing the through hole of the through hole of clamp and metal cover board, also has the valve body that constitutes the safety valve of one with clamp on the clamp, described safety valve body is mounted to safety valve after passing the through hole of metal cover board.
On the other hand, a kind of battery is provided, comprises battery cover board assembly and housing, described battery cover board assembly comprises metal cover board and the pole with through hole, also comprise clamp, described clamp is made by insulating material, has through hole on the clamp, after pole passes the through hole of the through hole of clamp and metal cover board, be fastened on the metal cover board, also have the valve body that constitutes the safety valve of one with clamp on the clamp, described safety valve body is mounted to safety valve after passing the through hole of metal cover board.
Adopt technical solutions of the utility model, for the battery that adopts metal cover board, is the clamp of one owing to employing between cover plate and pole has the location with insulation function, the battery of explosion relief valve is installed for needs, because valve body and clamp integral production with safety valve, on the one hand the mounting structure of safety valve is simplified, also made the easier realization of sealing effectiveness of safety valve on the other hand.Further, be implemented in the pole installation process, automatically pole is fixed, and can be connected with battery pack in the assembling of battery cover board assembly the time, prevent that pole from rotating, and makes the installation of pole more convenient, on the other hand on the one hand, also make the battery cover board assembly sealing of installation back tightr, solved headachy leakage problem.In a word, take battery cover board assembly of the present utility model, can overcome the metal cover board of existing battery and the installation process more complicated of safety valve and pole existence, and be difficult to the technical problem that fastening, easy appearance is leaked in the process of installing and fixing.Provide a kind of have be convenient to install and battery cover board assembly that sealing effectiveness is better new and the battery that has used this cover plate assembly.
